All blast holes deviate but without routine measurement we can’t fully understand the impact it has on blasting efficiency. As production hole drilling and blasting is the final process in extracting material to be sent to the mill or processing plant, it is important to get it right.
In-hole deviation is known to be a contributor to poor fragmentation, dilution, bridging and ore loss. The ability to measure deviation and adjust the blast or re-drill is now more achievable than ever with the DeviGyro RG30 continuous and lightweight survey system.
